Problems solved by technology

[0002] At present, my country mainly sprays pesticides on crops through low-volume or ultra-low-volume spraying; but one of the most important problems in the method is that the amount of supporting auxiliaries involved in low-altitude spraying is seriously insufficient, and the liquid medicine is easy to precipitate. easy to drift
[0003] In view of the above problems, the prior art mainly reduces the drift of droplets by adding anti-drifting additives, and vegetable oil is the main anti-drifting additive; however, vegetable oil has poor solubility, high volatility, high viscosity, High cost, complex and variable composition, unstable performance and other defects, its drift resistance and volatility resistance need to be improved

preparation example Construction

[0031] The present invention also provides a preparation method of the anti-flying additive described in the above-mentioned technical scheme, comprising the following steps:

[0032] Mix polyethylene glycol, polyglycerol ester, ethylene glycol diacetate, ethoxy-modified polytrisiloxane, wetting agent, glycerin and styrene-acrylic emulsion to obtain the anti-flying additive.

[0033] In the present invention, the mixing is preferably: mixing polyethylene glycol, polyglycerol ester, ethylene glycol diacetate, ethoxylated polytrisiloxane, wetting agent and glycerin to obtain a mixture ; Then mix the mixture with styrene-acrylic emulsion. The present invention does not have any special requirements on the mixing mode, temperature and time of the polyethylene glycol, polyglycerol ester, ethylene glycol diacetate, ethoxy-modified polytrisiloxane, wetting agent and glycerol. It is limited to use the mixing method, temperature and time well known to those skilled in the art to make ...

Embodiment 1

[0039] A kind of anti-fly additive, by weight, comprising: 20020 parts of polyethylene glycol, 20 parts of polyglycerin fatty acid ester, 20 parts of penetrating agent T, 20 parts of styrene-acrylic emulsion, 10 parts of ethylene glycol diacetate , 10 parts of ethoxylated polytrisiloxane, 60 parts of glycerol.

[0040] The preparation method of described anti-flying auxiliary agent:

[0041] Fully mix the polyethylene glycol, polyglycerol ester, ethylene glycol diacetate, ethoxy-modified polytrisiloxane, wetting agent and glycerol in the above parts by weight to obtain a mixture;

[0042] Under the condition of stirring, styrene-acrylic emulsion was added to the mixture and mixed for 30 minutes, and the stirring speed was kept at 30 r / min during the whole process to obtain the anti-flying additive.

Embodiment 2

[0044] A kind of anti-fly additive, by weight parts, comprising: 30 parts of polyethylene glycol 400, 30 parts of polyethylene glycol 600, 5 parts of polyglycerol ester monooleate, 5 parts of alkylphenol polyoxyethylene ether , 5 parts of styrene-acrylic emulsion, 20 parts of ethylene glycol diacetate, 20 parts of ethoxylated polytrisiloxane, and 60 parts of glycerin.

[0045] Refer to Example 1 for the preparation method.

Abstract

The invention relates to the technical field of pesticide adjuvants, in particular to a flying prevention adjuvant and a preparation method and application thereof. The flying prevention adjuvant provided by the invention comprises the following components in parts by weight: 20-60 parts of polyethylene glycol, 5-20 parts of polyglycerol ester, 5-20 parts of wetting agent, 5-20 parts of styrene-acrylic emulsion, 10-20 parts of ethylene glycol diacetate, 10-20 parts of ethoxy modified polytrisiloxane and 20-60 parts of glycerol. According to the embodiment of the invention, the flying prevention adjuvant has better anti-drift performance, and the drift inhibition rate is more than 70%, so that different liquid medicines all have better anti-transpiration performance, the evaporation time ismore than 149s, and the anti-drift performance and the anti-volatility performance of the flying prevention adjuvant are improved compared with the flying prevention adjuvant added with vegetable oil.

Description

technical field [0001] The invention relates to the technical field of pesticide adjuvants, in particular to a fly control adjuvant and its preparation method and application. Background technique [0002] At present, my country mainly sprays pesticides on crops through low-volume or ultra-low-volume spraying; however, one of the most important problems in the method is that the amount of supporting auxiliaries involved in low-altitude spraying is seriously insufficient, and the liquid medicine is easy to precipitate, and the spraying process is difficult. The liquid is easy to drift. [0003] In view of the above problems, the existing technology mainly reduces the drift of droplets by adding anti-drifting additives, and vegetable oil is the main anti-drifting additive; however, vegetable oil has poor solubility, high volatility, high viscosity, and Due to defects such as high cost, complex and variable composition, and unstable performance, its drift resistance and volatil...
